Fidelity sheetsFidelity Treasuries download includes all 600+ Treasuries, so I use this for BEI calculations. If you don't have a Fidelity account, you'll need to get quotes from somewhere else. Fidelity downloads include the download date and time in the last row of column A, so this can be used to reliably set the settlement date.
